Hurricane Isaias

Hazardous Marine Conditions

Extended Outlook

Isaias will remain well east of our region. However, will still expect hazardous Gulf seas/swell, along with strong rip currents, and the potential for minor coastal flooding.

A small craft advisory is in effect from 7 AM CDT Thursday through at least 1 AM CDT Saturday for the waters from High Island to the Matagorda Shipping Channel between 0 and 60 nautical miles. You can expect hazardous wind and wave conditions, featuring northeast winds of 15 to 25 knots with gusts up to 30 knots, and up to 35 knots well offshore, along with nearshore seas of 4 to 7 feet and offshore seas of 7 to 9 feet. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in these conditions.
